HEATING AND VENTILATING DRUM FOR STOVES.

SPECIFICATION forming part of Letters Patent No. 294,771, dated March11, 1884,

Application filed'June 1, 1883. (No modeld To all whom it may concern.-

Be it known that 1, JOHN F. DAVIS, a citizen of the United States,residing at Altoona, in the county of Blair and State of Pennsylvania,have invented certain new and useful Improvements in Heating andVentilating Drums for Stoves; and I do declare the following to beenfull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis specification.

This invention relates to a heating and ven tilating drum or'jacket forstoves; and it consists in the construction and arrangement" of parts,as hereinafter more fully described and claimed.

In the annexed drawings, illustrating the invention, Figures 1 and 2 aresectional elevations, and Fig. 3 is a side elevation, of a stoveprovided with my improved heating and ventilating drum or jacket, andillustrating different modes of arranging the air-inlet pipe.

A is a stove, of any suitable or ordinary construction. The fire-pot ofthis stove is surrounded with a jacket, B, to which cold air isintroduced through a cold-air pipe,.0,

having a valve or cut-off, D, by which the entrance of air is regulated.The jacket B is provided near the top with a series of openings, a a,controlled by slides or valves 12 b, and near the bottom of the jacketis a similar series of openings, 0 0, controlled by slidevalves (1 d. v

The cold air to be supplied to the drum or jacket B can be taken from aflue or from the exterior of the building or apartment in any convenientmanner, and the pipe 0 may be arranged partly beneath the floor, asshown in Fig. 1; or it can be passed upward, as shown in Fig. 3, to anysuitable source of pure air; or it may be passed into a flue, as shownin Fig. 2.

The operation of the device will be readily understood. By opening thevalve D of the cold-air pipe 0 and closing the slides 12 and d in thejacket B, cold air will be admitted into the jacket, and after havingits temperature raised by the heat of the stove it may be admitted tothe apartment by opening the upper slides, b b, of the heating andventilating jacket. NVhen a sufficient quantity of pure and heated airhas thus been permittedto enter the room, the valve D can be closed,and, if desired, the lower slides, d d, can then be opened, so as topermit "a circulation of air through the jacket, cold air entering fromthe room at the bottom and passing out heated at the top; or, by closingthe upper slides, I) b, and opening the lower slides, d d, the heatedair can be thrown downward to the feet.

By this simple contrivance aroom can be 6 readilyandsufficientlyventilated without subjecting its occupants to drafts.

I am aware that the base of a heating-stove has heretofore been providedat its bottom with an opening for the admission of the ex- 7 ternal airto a hot-air chamber beneath the fire-pot, an air flue or flues beingarranged in communication therewith and with the lower air-opening, saidair-flues having outlet-apertures for the escape of heated air. The baseof such stove has also been provided with an annular flue surroundingthe hot-air chamber, and through which the heat and products ofcombustion are caused to pass for the purpose of heating the upwardcurrents of air that enter and pass through said chamber.

Iam also aware that heating and ventilating drums or jackets for stovesare well known, and that such drums or jackets have been provided withregisters or valved openings for 85 controlling the escape of heatedair, cold air being conducted indirectly to such jackets throughsuitable pipes. These, however, I do notbroadly claim.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is.

The combination, with a stove, of the heat ing and ventilating drum orjacket *B, surrounding the fire-pot, and having side open- 5 ings, a. aand c 0, controlled by slides b b and d d, and the external cold-airpipe, 0, having a valve, D, all constructed and arranged as and for thepurpose described.

In testimony whereof I affix my signature in Ice presence of twowitnesses.
